LLOYD COLLIS, OF NEW YORK, N. Y.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 591 ,385 dated October12, 1897.

Application tiled March 8 1, 1 8 9 7.

T at whom it may concern: v

Be it known that I, LLOYD COLLIs, of New York, in the county of New Yorkand State of New York, haveinvented certain new and useful Improvementsin Oar-Couplings; and I do hereby declare the following to be a full,clear, and exact description of the same, reference being had to theaccompanying drawings, forming a part of this specification, and to theletters of reference marked thereon.

This invention relates to improvements in that class of twin-j awcouplings havinga horizontally-swinging knuckle or knuckles and a lockfor retaining the knuckleor knuckles in their closed or coupledposition, the object of the invention being to prolong the life of suchcouplings or to overcome the effects of wear coupling and to preservethe lines of the original coupling as nearly as practicable, suchwear-plate being held in position by a pin or through-bolt insertedthrough the opening ordinarily provided for adapting the coupling foruse with the common link and pin.

The invention further consists in certain novel details of constructionand combinations and arrangements of parts, all as will be nowdescribed, and pointed out particularly in the appended claims.

Referring to the accompanying drawings, Figure 1 is an elevation of awear-plate constructed in accordance with my present invention. Fig. 2is a similar view taken at right angles to Fig. 1. Fig. 3 is a top planView. Fig. 4 is an elevation illustrating the application of thewear-plate to a knuckle. Fig. 5 is an elevation of a clamp plate orblock preferably employed to lock the wear-plate in position, and Fig. 6is a top plan view of the same.

Like letters of reference in the several figures indicate the sameparts.

In carrying my present invention into practice I provide a verticalwear-plate adapted to be clamped against the inner wearing-face of theknuckle and preferably having overhanging lips or edges extending aboveand Serial No. 630,124. (No model.)

below the knuckle for a purpose to be presently explained, although suchoverhanging portions are not essential, said wearing-plate beingpreferably clamped in position by a central enlargement or extensionadapted to pass into the opening ordinarily left in the knuckle for theinsertion of a link and held by a transverse pin or other suitablemeans, as will be readily understood. The central enlargement of thewearing-plate, extending as it does into an opening in the knuckle, ispractically contained within the body of the knuckle itself, and hencethere are no projecting parts liable to be derangedor to be broken inusage save the plate itself, and this is in such position" that it iscompletely supported and braced by the knuckle and receives no strainssave a compression and friction such as ordinarily wear away the innerface of the knuckle.

Referring to the accompanying drawings, 19 indicates a plate made of alength and width substantially corresponding to that portion of theinner face of the knuckle which receives the wear or rubbing action ofthe corresponding face of the cooperating knuckle. Arranged centrallyand preferably formed integral with the plate I) is an enlargement oreX- tension 0, approximating in cross-sectional area the area of thecentral opening in the knuckle adapted for the insertion of a link. Thisenlargement a may be substantially solid or of open-work, and in thepreferred construction it is formed with two intersecting apertures,one, h, Fig. 3, adapted to fall in line. with the vertical pin-openingin the knuckle, and the other, 61, Fig. 2, adapted for the insertion ofa locking plate or block e, the base of which extends into said opening,as shown in said Fig. 3, while its end projects into the opening h inposition to bear against the pin 70, Fig. 4., at a point opposite theplate b in order to draw said plate I) firmly against the inner face ofthe knuckle. A set-screw g or other appropriate clamping mechanism maybe employed for forcing the .plate e against the pin, or, if desired,the plate or block 6 may be omitted and the clampingscrew or otherwell-known clamping device operate directly against the pin itself.

. Extending out to one side of the central enlargement c are twoprojections f, adapted to seat against the rear wall of the link-openingZ, Fig. 4, although it will be noted that the body of the enlargement 0may be extended for this purpose, if so desired. The projections f arepreferably employed, however, inasmuch as theymaybe made normally largeand easily cut down by a file or otherwise to secure an accurate fit. Tofurther insure a proper retention of the plate Z) under all conditionsof use, Ipreferably form flanges a at top and bottom thereof adapted totake over the edges of the knuckle, such flanges being undercut orhaving grooves m therein to accommodate or receive any burs which mayhave been formed at the edges of the knuckle because of the wear andpressure thereon; but it will be noted that these flanges may beomitted, if so desired,

It will be observed that knuckles which have become so worn as to bepractically useless may with the employment of my invention be restoredto practically their original lines, and when one plate has been worn orbroken another may be cheaply and quickly substituted, therebypractically prolonging the life of the knuckle indefinitely.

Having thus described my invention, what I claim as new is- 1.Awearing-plateforcar-coupler knuckles having a verticallyelongated bodyportion conforming substantially to the lines of the wearing-face of theknuckle, a central enlargement 011 the rear face of said wear-platehaving a vertical aperture therein for the re ception of a pin and alock working in said aperture for locking the plate to the pin;substantially as described.

2; A wearing-plate for the knuckles of earcouplers having thevertically-elon gated body conforming approximately to the lines of thewearing-surface of the knuckle, a central e11- largement or projectionon the rear face of said wear-plate and end flanges adapted to take overthe bottom and top edges of the knuckle; substantially as described.

3. A wearing-plate for the knuckles of earcouplers having avertically-elongated body and conforming approximately to the lines ofthe wearing-surface of the knuckle, a central projection or enlargementon the rear face of the wearing-plate and undercut end flanges fortaking over the top and bottom edges of the knuckle; substantially asdescribed.

4. The combination with the horizontallyswinging knuckle of acar-coupling having an ordinary link-opening in its forward portion anda pin-openingintersecting said link-opening, of a wear-plate having awearing-face corresponding approximately to the lines of thewearing-face of the knuckle and -a centrally-arranged projection on itsrear face adapted to fit into the link-opening with an aperture adaptedto register with the pinopening and a pin passing through said openingto retain the wear-plate in position; substantially as described.
